Ideas
I'm having this issue now too. I reset the toddler back to baby. I'm now hating playing. Can't reduce the Fundamentals so I can't reach the milestones. I'd have thought I'd have kept the ones baby got last time he was a toddler but nope they were all reset when I de-aged him to baby again!
New pack due and I've pre-ordered. I've literally bought every pack no mods or cc. Update my pc and EA app everytime it is needed. You'd think I'd be fine. My game keeps crashing. Takes forever to open the fridge. It's like it's thinking about it. And if they are going to do anything, it takes a while for them to move. I know it's not my laptop because it's not old and I just paid £1200 for a top gaming laptop so It can handle the packs but for some reason, it's just not running as good as I'd expect it too.
